Mesh Extender for Blender

Mesh Extender for Blender

Mesh Extender is a fast, interactive modeling tool for extending mesh geometry along the local X, Y, and Z axes.

Instead of manually cutting, moving, and bridging geometry, simply activate the tool and drag its custom viewport handles. The mesh is split through its center, both sides move symmetrically in opposite directions, and the space between them is automatically bridged, while preserving existing edge properties.
